Abstract: It is an intriguing possibility that dark matter (DM) could have flavor quantum numbers like the quarks. We propose and investigate a class of UV-complete models of this kind, in which the dark matter is in a scalar triplet of an SU(3) flavor symmetry, and interacts with quarks via a colored flavor-singlet fermionic mediator. Such mediators could be discovered at the LHC if their masses are $\ensuremath{\sim}1\text{ }\text{ }\mathrm{TeV}$. We constrain the DM-mediator couplings using relic abundance, direct detection, and flavor-changing neutral-current considerations. We find that, for reasonable values of its couplings, scalar flavored DM can contribute significantly to the real and imaginary parts of the ${B}_{s}\ensuremath{-}{\overline{B}}_{s}$ mixing amplitude. We further assess the potential for such models to explain the Galactic center GeV gamma-ray excess.
